Archery bowstring releasing device

Abstract

A tensional line release device with an adjustable, 360 degrees rotatable pull handle permitting smooth, steady release by a single finger trigger squeeze of a tensional line such as an archer bowstring allowing the maintenance of a stabilized aim. The device is composed of a tensional string retention chamber containing two contiguous, line impinging spheres, mounted in an inner journal, which are held together in an impinging position by inward pressure applied on the diametrically opposite points of the spheres by an external journal of the mechanism. Activation of the trigger mechanism results in movement of the external yoke decreasing the inward pressure on the two spheres so that impinging pressure contact between the two contiguous spheres is instantaneously overcome by the tension on the line causing it to slip between the spheres in a smooth release in a forward direction with no imposed horizontal oscillation or vertical bind.

What I claim is: 
     
       1. A device adapted to draw back a bowstring on a bow away from a target and toward an archer using said bow to a predetermined position holding said bowstring and releasing said bowstring by finger actuation of the device, comprising: a rigid shaft having a bifurcated end;   grasping means for manually holding the shaft rotatably connected at one end opposite the bifurcated end of said shaft;   a pair of spherically-shaped bowstring impinging members, each member being located in said bifurcated shaft, the size and shape of said bifurcated shaft selected so that one of said pair of spherically-shaped bowstring impinging members will locate at one horizontal side of said bifurcated shaft and the other of said pair of spherically-shaped bowstring impinging members will locate at the other horizontal side of said bifurcated shaft;   impinging member retaining means movably connected to said shaft, said impinging member retaining means having a first position for forcing said impinging members firmly into contact with each other to restrain a bowstring on the side of said impinging members nearest the archer within said bifurcated end of said shaft and which is movable to a second position allowing said impinging members to separate a sufficient distance to allow a bowstring to pass between said impinging members; and   a finger-actuated means operatively connected to said impinging member retaining means said finger-actuated means being pivoted to disengage said impinging means, member retaining as to permit said retaining means to move independently from said first position to said second position.   
     
     
       2. A device for drawing back a bowstring as in claim 1 including: a biasing means for resiliently holding said retaining means in said first position.   
     
     
       3. A device for drawing back a bowstring as in claim 2, wherein said finger-actuated means is pivotably connected to said shaft. 
     
     
       4. A device for drawing back a bowstring as in claim 3, wherein: said finger-actuated means includes a housing means for creating a greater distance between said finger-actuated means and said pivotal connection to said impinging member retaining means.   
     
     
       5. A device for drawing back a bowstring as in claim 2, wherein: said impinging member retaining means is slideably connected to said shaft.   
     
     
       6. A device for drawing back a bowstring as in claim 5, wherein: said biasing means is contained within said shaft and connected to said impinging member retaining means.
